This invention relates to an improved machine for automatically s reading and cuttin bar-shaped lengths o dough-pieces, the

' sai machine working quite automatically and solely calls for manual attendance when suspending thelengths of dough-pieces from I rakes, which are suspended in the device, and when removing the frame covered with the dough-pieces. a

A machine constructed according to the present invention is illustrated byway of example oh the accompanying sheet of drawi in whi Y I i 1 and 2 show themachine in side view 15 and ont'view respectively. Fig. 3 iiia detail view, and

Fig. 4 illustrates the operation of the ma-- chine when putting aside the empty frames. In Figs. 1 and 2, the characters 1 and 2 no designate the frame of the machine, 3 designates a table, which is constructed in the sha of horizontally disposed slides for guiding the frames carrying the dough- P ieoes. as The stock, indicated in dotted lines in Fig.

2, is kept ready on the inclined plane E and always the foremostfiframe of thisstock is folded down into the sition 4"," in which it is ready for being fe into the machine. so The following automatic device is provided for "arranging the lengths of doughpieces (for instance macaroni) on the horizogltagframe, disposed atthe time on the ta e passin over the three sets of chain-wheels 8 9 an 10 arranged at both sides of the machine, are connected with each other at a number of places, for instance at two places, by means of two successive transverse bars 12, 13 and 12, 13" respectively, which are arranged at short distances apart. Shortcranks 15 are mounted freely rotatable on the shaft 14 of the two chain-wheels 10 andmay be rotated in the direction of the arrow shown in Fi 1, whereby a spring is placed in tension. e upper ends of the said cranks are connected with each other and form an.

so ,open swinging frame. Adisc 17 is mounted i are parallel disposed on the frame 4, as indi- Chain-wheels 8, 9 and 10 are arranged in ines pairs in the posts 5, 6"and 7. Chains 11,-

' as indicated in dotted lines, the sheet-metal freely rotatable on cantilevers 16 of the frame of the machine underneath each chainwheel 10, and alternately a groove 18 and a feed-tooth 19 are provided-on thecircumference of each disc. e a

It is assumed, that both .discs 17 (Fig. 1) are disposed 1211811611 a manner, that a groove 18 is located at the apex. Two lateral pro jections 20 of sheet-metal hooks 21 engage this oove, each ofthese hooks being provid with abottom mouth'22 and a to mouth 23, and both hooks are connected wit each other by a transverse rake 24, provided with a suitable number of uniforml dis-- tanced prongs 25. ,As shown in dot lines in Fig. 2, the finished lengths of dough-pieces (macaroni) are placed by hand onto the said prongs. 1

Now if the chain-gear is rotated in the direction of the arrows, the transverse bar 12 moving in advance in Fig; 1 co-operates at both sides with the feed-teeth 19 of the discs 17, which at the time are disposed in its path of movement, and thus rotates both discs to such an extent, that the two hooks 21 take up the 'tion shown in Fi .1. In this ition the ttom mouth 22 is isposed in t e path of movement of the transverse bar 13 which immediately follows. Now this transverse bar enters at both sides the mouths 22 and draws the rake together with the suspended len hs of dough-pieces across the frame 4, resting on the table, so that the dough-pieces cated in dotted inFig. 1. Whenever the rake, fed by the transverse bar 13, has reached the end of the machine at the right-hand side hooks will be inclined b stops A at both sides of the machine -in suc a manner, that the prongs 25 slip out of the dough-loops resting on the frame 4. The empty rakes are fed forward in the direction of rotation of the chaingear and move in front of the swin 'ng frame 15,'15,-15. The top months 23 o the books 21 engage both sides of the transverse bar 15", so that the empty rakes are suspended now from this transverse bar. Thereafter the ends of the transverse bar 13, fed by the driving chain 11, strike against the plate springs 15", arranged on the cranks 15 at both sides, and thereby feed the swinging frame 15, 15, 15 to such an extent whereby the tension of the springs 15 is gradually increased, until the transverse bar 13 (in the position shownin Fig. 4) slides past the bent plate spring 15. In-this position in which the swinging frame 15 just has disposed, by the aid of its books, the rake 24 in the grooves 18 of the discs 17 the cams D rotating with the chain 11 at both sides co-operate with the ears N of the hooks and turn both hooks in the direction of the arrow (Fig. 4) in such a manner, that the transverse bar 15 of the swinging frame is released and now the whole frame 15 amps back into the initial position by the aid of the springs 15.

Now the dough-pieces can be again suspended from the prongs of the rake.

The frames 4 supplied with a rake of dough-pieces, arranged in parallel rows, are shifted, for a width of the frame, on the table 3 transverse to the direction of the lengths of dough-pieces Thereby the frames pass underneath two circular cutters M, which cut oil the ends of the lengths of dough-pieces, so that the pieces of dough are cut at exactl uniform length and move forward to be ried. The removed frame 4 is replaced on the table 3 by a frame from the stock of frames in Fig- 2.
